1. DBTrace: DBTrace is a feature in the Performance Analysis Tool (PAL) that creates a detailed log of calls to the PegaRULES database. DBTrace displays SQL statements sent to the database and the time spent for each operation.PAL: This data is stored in “PAL counters” or “PAL readings.” PAL stands for Performance AnaLyzer, and is a collection of counters and timer readings, stored in the requestor, that an application developer could use to analyze performance issues in a system.PAL Features • Add Reading • Add Reading with Clipboard Size • Reset Data • Save Data • Start DBTrace • DBTrace Options • Start Profiler • Show Graph • My Alerts Alerts: During application processing, Process Commander writes to the performance alert log a sequence of text entries called alert messages that identify mainly performance-related issues or errors. The performance alert log is usually named PegaRULES-ALERT-YYYY-MMM-DD log.AES: Exceptions are processed in a similar way as alerts. When a Process Commander server generates exceptions they are sent by SOAP to the AES system. The system parses the exceptions and stores the records in the pegaam_exception table in the AES database. Based upon how often an exception occurs and the system events that triggered those exceptions, AES aggregates these records into work objects called AES exception items. These items are written to the AES database in the pegaam_exception_work table.
